NON-REFILLABLE- BOTTLE.

SPECIFICATION forming` part of Letters Patent No. 653,624, dated July 10, 1900.

Application filed May 28, 1900.

To all whom, it may concern: A i

Be it known that I, GEORGE S. LINTHIGUM, a citizen of the United States, residing at Baltimore, in the vState of Maryland, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification. y

My invention relates to non-refillable bot-v tles; and its object is to provide a bottle of this character which although of few and simple parts will eectually prevent any one from refilling it after it has once been emptied of its original contents. v

Reference is to be had to the accompanying drawings, in which- Figure l is a vertical section of the bottle, and Fig. 2 is an enlarged side elevation of the valve detached.

Referring to the drawings, A designates the neck of a bottle having two annular recesses a and b on its interior at its lower end.

B designates an elastic valve, preferably formed of rubber and of approximately conical or funnel-shaped form inverted. Said valve has a thickened base rim-ange d, which springs out by its own elasticity into the lowermost annular recess a, which thus holds the valve in place. Near its upper end the elastic valve B has an approximately-spherical bulb e, above which is a tapered apex f, which is formed with a plurality of longitudinal slits g, extending radially from its tip and terminating at the bulb.

In the bottle-neckA above the elastic valve B is located a guard O, preferably formed of glass and in the form of a truncated cone. This guard has at its base an annular flange h, which fits accurately in the bottle-neck AA and is formed with an annular groove or recess i, adapted to coincide with the uppermost interior recess o. In said recess t' is located an outwardly-springing split ring 70,'

which takes in the said annular recess b, and

thereby holds the guard O securely in place.

The guard O is further formed with acentral upwardly-tapering cavity l, whose walls fit closely around and'contact with the exterior part of the funnel-shaped elastic valve B. Above this cavity is an enlarged outletchamber m, having a slightly-contracted bottom flange m', which supports the said bulb,

as shown, the bulb e and apexfbeing in the chamber m. Discharge-passages n are formed in the side walls of said chamber/m and lead therefrom in a downwardly-inclined direc- At its top or small part the cone-guard C is provided with a circular baiile-plate o,

projecting out over the discharge-passages n and serving to deflect a wire or any like device which might be inserted in the bottleneck in an attempt to fraudulently open the valve. The mouth of the bottle is closed by a stopperp in the usual manner.

When the bottle is inverted to pour out its liquid contents, the weight of the liquid will open the slits g in the apex of the valve and the liquid will pass out through the outletchamber fm and discharge-passages n, and the construction of the guard O, with its tapering cavity Z fitting closely in contact with the valve, forms a rigid support forthe valve and overcomes the tendency of the Weight of the liquid to dislodge the valve from its placer When the bottle is again restored to normal position, the slits g automatically close by the elasticity of the material and a partial vacuum is momentarily. formed within the rubber valve, which tends to collapse the latter; but this tendency is overcome by the spherical bulb e, which, as shown in Fig. 1, is expanded Within the chamber and rests upon and is supported by the bottom flange m', whereby said bulb prevents any down- Ward collapsing movement of that portion of the valve below it, and at the same time the bulb forms a strengthening base or support for the slitted apex f.

The arrangement of the outlet-passages n, leading from the outlet-chamber 'm in a downwardly-inclined direction, and the bafle-plate o eectually prevents the insertion of a wire or similar instrument to reach the slitted apex f for the purpose of refilling the bottle.

Havingv thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A non-refillable bottle providedl in its neck with an interior annular recess; an elastic 4conical valve having a base rim-ange held by its own elasticity' in said annular recess and an apex provided with longitudinal slits; and a guard in the bottle-neck hav- IOO ing a central tapering cavity lwhose. walls it closely in contact with said valve and terminating below the said apex, and provided with an outlet-chamber surrounding said apex, and with downwardly-inclined discharge-passages leading outwardly from said outlet-chamber.

2. A non-rellable bott-le provided in its neck with an interior annular recess; an elastic conical valve having a base rim-flange held by its own elasticity in said annular recess, said valve also having a spherical bulb near its upper eudand a tapered apex above said bulb having longitudinal slits extending from its tip and terminating at the said bulb; and a guard in the bottle-neck havinga central tapering cavity whose Walls closely coutact with said valve and terminate at the lower side of said spherical bulb, an outletchamber surrounding said apex and spherical bulb and provided with a bottom dan ge which supports the bulb, and discharge-passages leading from said outlet-chamber.

3. A non-relllable bottle provided in its neck with two interior annular recesses a, b;

an elastic conical valve having a base rimilange held by its own elasticity in the annular recess a, said valve also having a bulb near its upper end and a tapered apex above said bulb having a plurality of longitudinal slits extending from its tip to the bulb; a guard in said bottle-neck having an annular base-,flange formed with an annular recess i coinciding with the uppermost recess b-said guard also having a central tapering cavity
